Be it known that l. Nils ll. Ax'orn e-s. a eitizen ot' the l'nitedtates. ref. inn; at Middletown. in the eountv ol Middlesex and State ot(onneetirut. have invented emain new and uset'ul lniprovetnent-- in'lvpe- \Yriting' Machines. ot vhit-ll the l'ollowhu; is a full. elear.and exaet l (lll7ti tl. ueh as will enahle others skilled in the art towhieh it appertains to malze and use the same.

'lhis invention relates to t \pe\\'l'ltill' t maehines. and with regardto eer ill] more speeitie l'eatures thereot. to the meehanism known tothme l'amiliar with the prattieal operation ol' a tvpetvriting nlaehtne.as an alining: seale or eartl holder.

()ne of the ol jeets ot the present invention is to provide a simple andpraetieal devii'e ot' the ahove haraeter which will he ellieient inoperation.

Another ohjeet is to provide an improved t'orm ot' alining sealeindieating i lit) at alt times the exaet, printin; point.

In the aeeompanving drawing. in whirh is illustrated one of the variouspossible em llodiments ot the several features of the invention. Figure1 is a plan view showing sueh parts of a typewriting machine as arenQePsSHly to illustrate the application ot' the present inventionthereto Fig. is a side levation of the parts shown in Fig. 1; Fig. 3 i.ii front elevation with eertain parts lit-in; shown in startion. orhrolten away. for the sake of elearness.

imilar rel'erenee eharaeters refer to similar parts throughout thetlitlerent views of the drawing.

While the pres nt invention will he tile, serilletl hereinat'tw withrelation to its appiieation to a noiseless tvpewritinglf machine in whi-h the type earriers are radially tllS posed with respeet to a eonunonprinting point and oaet with th platen by pressure in "mtradistitn-tionto impart. it i of nurse. t he nndewtood that this meehanism niav he.applied to other forms of t) pe- 'writim: maehines as well withoutdeparting deserilie anv torni ot tvpe aetl n and ass eia ed a,

in those l as the tunrtions are well lauown ainiliar with the arltel'erl-ing' now in detail iv the aerompanving' drawing and morepartimlarlv to Figs. 1 and 2. a platen roller 1 is carried by a earria'e 2 traveling along: a horizontally disposed shift rail :3 in the usualwell-known manner. letwe n the end wails l f the platen earriae'e andpositioned adjacent o the platen roller is a flat ;-heet-metal platenadapted t talt'e up he thrust or pressure the type tarriers one o\\illt'll is indr rated at i "th pap r is adapted to he ted downwardalvout the platen roller from a pap r tal'le t). and upward o er theflat pla n ext nding aer ss the l'ront ol the platen roller.

.\mon;1 the several meam used l'or hold" ing the. paper in engagementwith the platen. there is provided what will be termed hereinafter toreonvenienee. an alining scale" 7 of flat sheet metal provided withlaterallv extending arms at earh side eo-aeting with a relatively larges'art'ar of the flat platen I). or havin; a t tal spread of perhaps haltthe length of the platen roller, This seale. whit-l1 is ul ti aprinting; point indleator. is provided. al.-.o with downward twtendin;2ll'lll, ltl lormed Y MWWAWWWWH ill integrally with the lateral arms andhaving rearward extending ears 11 attheir lower ends. through slots inwhich pass adjusting screws 1; engaging tapped-out portions on anauxiliary bracket 13 carried by a main bracket ll secured in any desiredmanner to the shift rail 1) along which the carriage travels. It is tobe noted that the arms 8 and 1" carrying the scale 7 are. all ()1 onepiece. but not necessarily so, it being easier and cheaper to make theparts in this manner. The auxiliary bracket 13 as shown more clearly indetail. Fig. 3. is mounted upon trunnions in the form of adjustingscrews 15 passing through the sides of the main bracket ll and providedwith lock nuts 16 in order to maintain them in adjusted position. Thescrews passing through the ears 11 in the alimng scale are adapted topermit an independent vertical adjustment ol the alinint: s ale T inorder that it may properly coact with the lower edge of the printingline. The. adjusting screws 15 supporting the aux iliary bracket areparticularly adapted to permit lateral adjustment in order that theindices upon the alining scale 7 may properly coact with the centralportion of each printed character. the vertical and lateral adjustmentsbeing capabl oi being made independently of each other. It, is. ofcourse. to be understood that atter these adjustm nts are once made.further adiustments will probably be, unnecessary.

The alining scale 7 is spring pressed against the platen or paper. it inplace, by a flat spring 17. secured by means ot a set screw IN to therear of the main bracket ll. which bears against the upper ed e of theauxiliary bracket l as shown in lig. 2.

Th right and lelt hand ends of the alining ?ll( proper are onnectedacross the open renter exposing tin printing point by an upwardlyextending arch d portion 20 whi h i al o ruricd backwa d above theprinting point. as rllwz' a in Fig. 2. thereby to detlect the paper andhold the same in contact with the platen roller.

The hape of the central opening in the upward extending portion itthrough which the type pass when making the printed inr pres ion. is ol'importance. since it. guides the l'eeding ol the paper. and du to thecurved arch particularly prevents the cor-- tiers of the paper fromcatching in the opening it the corner happens to be just above the inneredge ol the laterally extending portion N ol the scale when the carriageis inoyetl to right or let't. or it the paper is l'ed into tlumachine insuch position that th orn r thereol'. would tend to enter or pass out ofthe opening. The inner ends of the latcrallj, extending arms H of thealiniug scale are turned slightly l'orward away from the platen as shownat 3] in Fig. l to prethe printing point.

vent catching of the paper during the letterspace movement of thecarriage. The upper end of the arched connecting portion 20 is providedwith a V-shaped notch, the space between the two upper points of whichrepresents the writing space or width of one letter and the bottom ofthe point of the V being directly above the center of In a machine usingthe pica type, for example, the printing space would be .10, so that theopening of the V would be of that amount in such a machine. The twoupper points of the V are also a certain number oi lines above thenormal writing line so that when inserting a character the space inwhich the same is to be inserted, is brought into alinement with thepoints of the V and then the paper is fed backward to the printing line.the line-space mechanism of the platen roller coi'itrolling accuratelythe position thereof. In order that the writing line may be exposed asmuch as possible, the scale is provided with openings 24 at each side ofthe printing point which assist in making the line being written. asnear visible at all times as possible.

In a double-shitt machine using straight thrust type carriers in whichthe type are positioned one above the other with their printing surfacesin substantially the same plane. there is, when writing a large numberof sheets a tendency for the upper and lower type to overscore orunderscore the printing line. The present alining scalchas an importantrelation with the paper-feeding qualities of a machine of thischaracter, as it holds the paper more closely against the platen mileandback of the plane of the flat platen thereby preventing buckling orswelling of the paper at the printing point. thuseliininating thetendency to overscore and underscore during the printing operation. Theoven-scoring is prevented by the rearward curved arched portion 20,

while the underscoring is prevented by means of a plurality of flexiblespring arms or lingers 25 riveted to the arms 10 supporting the aliningscale. These arms 23 extend backward against the platen roller, asclearly shown in Fig. 2 and are made of relatively light resilientmaterial to hold the paper against the platen roller just below the flatplaten 5. thereby materially assisting in the elimination of thetendency to underscore.

The present device tray serve either as an alining scale or a cardholder, but when intended to hold cards it is preferred to introduceadditional spring tension intermediate the scale. and final point oiresistance. This mechanism comprises a resilient arm it; extendingdownward l'rom the auxiliary bracket and is provided with a forward eXllt) trailing; pnrtiun 27. the, forward einl of whil-h forms a heel; tnengage a pull wire 01' eenneeting link .30 extending tawanl the front ofthe maehine.
